The greatest risk of tuberculosis transmission occurs when a patient with active TB does what?

Explanation:
TB is spread through the air, so the biggest transmission risk comes when an actively infected person coughs. Coughing releases tiny respiratory droplets that can contain the bacteria and stay suspended in the air, especially in enclosed or poorly ventilated spaces, making inhalation by others more likely. Activities like sleeping, eating, or bathing don’t generate these infectious aerosols in meaningful amounts, so they pose far less risk. In practice, this is why healthcare workers use airborne precautions and protective masks when dealing with a coughing patient suspected of TB.
